Casio LK-43. The completed machine. Lots of NOISE bends. Another thrift store special. This one was cheap because someone had pushed too hard on the 'Step 3' button in the '3-Step Lesson' section and broke the circuit board underneath, so it wouldn't play. Just needed a few jumpers soldered in across the cracked board and it worked great. This machine has MIDI in and out too, so that makes it even better! I can run a MIDI track from a sequencer while fiddling with the bends. Sweet!
